WebQuestion Write the maximum and minimum values of cos (cos x). Solution 1 ≤cos(x) ≤1forx ∈[0,x,π] cos (x)is maximum at x =π. cos [cos (0)]=cos (1)=0.9984 cos [cos (x)]=cos (-1)=cos (1) cos(cos(π 2)) =cos(0) =1 The maximum value of cos (cos (x))is 1. The minimum value of cos (cos (x))is cos (1). Suggest Corrections 5 Similar questions Q. WebJun 28, 2024 · Then, you want to find the minimum of sin 2 k x + cos 2 k x = ( 1 − cos 2 x) k + ( cos 2 x) k over all x ∈ R. Because cos is surjective on [ − 1, 1], it is equivalent to minimize f ( u) = ( 1 − u) k + u k over all u ∈ [ 0, 1]. For that, you can differentiate the (smooth) function f.
